ABSTRACT:
The present invention relates to an electrical relay in which a solid slug is moved within a channel and used to make or break an electrical connection. The solid slug is moved by electromagnets. In the preferred embodiment, the slug is wetted by a conducting liquid, such as liquid metal, that also adheres to wettable contact pads within the channel to provide a latching mechanism. The relay is amenable to manufacture by micro-machiningtechniques.
